Evaluating health service delivery to children with chronic conditions and their families: Development of a refined Measure of Processes of Care (MPOC-20)

This article describes the development of a shorter and improved version of the 56-item Measure of Processes of Care (MPOC) to create MPOC-20. MPOC is a measure of parents' perceptions of the extent to which specific behaviors of health care professionals occur. MPOC-20 is a self-administered, parent-completed questionnaire that was derived from the original MPOC, using both conceptual and empirical approaches. Further refinements to MPOC-20 were made in its formatting and clarity of response options. MPOC-20 retains the same conceptual structure of five scales that reflect the essential features of family-centered service. We provide evidence of good internal consistency, reliability, and validity using pre-existing data sets and a new independent sample from a province-wide survey. MPOC-20 offers users a measurement option that is useful for program evaluation and quality assurance activities as well as for research purposes.
